The United States Thursday sanctioned individuals and companies for providing financial services to and facilitating weapons procurement for Hezbollah, the Treasury Department said.

The Treasury Department's Office of Foreign Assets Control (OFAC) took action against two individuals and two companies based in Lebanon for providing financial services to Hezbollah, along with an additional individual involved in facilitating weapons procurement for the group, it said in a statement.

Founded in 1982 by Iran's Revolutionary Guards and classified by the United States and other Western countries as a "terrorist organization," Hezbollah is a powerful group in Lebanon and acts as a proxy for the Islamic Republic. It has been fighting in Syria with other Iran-backed forces.

OFAC regulations generally prohibit all dealings by US persons or within the United States that involve any property or interests in property of designated entities.

Among the individuals sanctioned on Thursday were Adel Mohamad Mansour, who led a Hezbollah-run quasi-financial institution; Hassan Khalil, who worked to procure weapons on behalf of Hezbollah; and Naser Hassan Neser, who worked with an entity that provided financial services to the group, the Treasury Department said.

The two companies sanctioned on Thursday over providing financial services to Hezbollah were named Al-Khobara and Auditors.

Last month, the United States issued sanctions against an international oil smuggling network it said supports Hezbollah and Iran's Quds Force, targeting dozens of people, companies and tankers.
